McAdams Excavation & Landscaping does the dirt-and-stone work behind a yard: drains, grading, retaining walls and stone edging. A 2026 customer had an old stone and cement wall removed, a wooden retaining wall replaced with a stone one and the front lawn filled in, and said everything came out beautifully. It holds 4.7 stars from 21 ratings on Angi and on HomeAdvisor, and a 2023 customer described Rowan and Ken as the father-and-son owners. A 2023 customer said McAdams installed French drains around the house after the basement flooded for the first time in 16 years, then landscaped the part of the yard that had been excavated. That 2023 customer said Rowan took the time to listen and offered various solutions, after quotes from other companies came in very high. A 2022 customer with a farmhouse over 200 years old said Ken and his sons cleared massive overgrowth and tall bushes growing through outside wiring within a week, without interfering with the wiring, and graded the property to help with water drainage. A 2022 customer said Ken and Rowen installed Round River Rock Stone along about 180 feet of both sides of a driveway: material was excavated to a 3-inch depth, landscape fabric went down, then the stone. A 2022 customer said Ken and Rowan added curbing along three sides of a large pea stone patio area, refreshed the pea stone between pavers on a long walkway, and got the project done within a tight timeframe. A 2022 customer described a drainage, landscape and hardscape project with Ken, Rowan and Roger that included retrofitting new stone materials into a patio with old granite curbing. In 2021, a customer said Ken measured for a retaining wall, came back that afternoon with his team for more precise measurements, and had a quote to the customer that evening that the customer called fairly priced. A 2026 customer gave one star after Ken came out about replacing and installing an exterior French drain along the back of the house, where a frost heave had lifted the corner of the house over the winter; that customer said Ken also suggested heat tape for the drain pipe and said it came with a 10-year warranty. A 2021 customer gave two stars, saying damage was done to the house, the repair was not finished, and the promised contact had not happened.
The work was done efficiently and we'll. We had an old stone and cement wall removed, a wooden retaining wall replaced with a stone one and the front lawn filled in. Everything came out beautifully. They take pride in their work and it shows.
What to say about McAdams Excavation. When I first contacted them, Ken was very friendly and set up a time to come out to the house and go over the scope of the project that we needed done. When he came out he looked at everything and said he would put together a quote and get back to me. The initial project was to replace and install a new exterior French drain along the back of the house that we had a problem with over the winter with a frost heave actually lifting the corner of the house. He also suggested that he should put heat tape into the drain pipe to keep them from freezing during the winter, he went as far to say they would automatically come on when the weather got cold and turn off when everything warmed up in the spring and they came with a 10 year warranty. Then he pointed out that there was old asphalt out there and it should be removed so they could regrade the surface under the deck and the entire backyard to have the water drain away from the house. He also pointed
Very excellent to work with, very understanding, very timely, very professional, and just precise on what they do .
Weâ ve done a lot of work on our house, and McAdams is easily one of the best organizations our family has had the pleasure of working with. Both owners, Rowan and Ken (a dynamic father / son duo), are highly collaborative and friendly individuals. The entire experience, from initial project scoping, through to the site walk through and job execution felt more akin to a partnership than hiring a contractor. These guys really listened, understood what a we were looking for, and were super creative in finding the right solution that fit our budget. Ken & Rowan went above and beyond to ensure that we were informed at every stage of the process, were open to mid-project modifications, and always went the extra mile to make sure everything looked perfect. They transformed the exterior of our home, and we couldnâ t be more pleased. We canâ t wait to hire them for more projects in the future!
This father and son duo team were just amazing. They had accommodated my changes I requested throughout our project and we couldn't be more satisfied with the outcome. They were absolutely amazing and just a pleasure to work with during the whole project. Just an incredible team!! I highly recommend this company for all your excavating needs!!
